JOSIAH O. WARD, OF ORANGE, NEW JERSEY.

H EM P-BRAKE.

SPECIFICATION forming part of Letters Patent No. 480,354, dated August 9, 1892.

Application filed January 12, 1892. Serial No. 417,822. (No model.)

To all whom it may concern,.-

Be it known thatl, JosIAH O. WARD, a citizen of the United States, residing at Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Hemp-Brakes, of which the following is a specification.

My invention relates to a modification of the hemp-brake shown in Letters Patent No. 465,433, granted J. J. Hawkius,December 15, 1891.

The object of this invention is to provide a hemp-brake which will readily clean the hurds out in a novel manner, as well as break the stock and deliver the fiber in a proper manner for a final separation.

Figure l is a central vertical section of my improvement. Fig. 2 is a similar view of a modification. Fig. 3 is a detail view of the fenders. Fig. 4 is a plan view of a section of the belt or carrier.

l represents the riddle-breaker; 2, the feedrolls.

3 represents the table; 4, the housing of the machine; 5,thecorrugateddelivery-rolls. The various parts are constructed in substantially the same manner as shown in said Hawkins patent.

7 represents a stationary break-bar, between which and the arms 8 of the riddlebeater the hemp is broken downwardly instead of upwardly.

9 represents a series of fenders, which serve two purposes: first, to direct the hemp onto the endless carrier, and, second, to allow the hurds to fall through between the fenders while the hemp is dropping down onto the apron.

10 represents an endless apron passing over drums ll l2. The endless apron may be made of open wire or of slats similar to straw-carriers, which allow the hurds to sift and drop through. The endless apron lO delivers the hemp to the corrugated rolls 5, where the joints and harder portions are crushed appropriately for the final cleaning of the same.

The modification shown in Fig. 2 is substantially the same except the endless belt is taut while that lin Fig. l is allowed to sag in the center. The hurds will pass through the endless carrier at the point a and from the under side of the hemp between the slats b. These slats are attached at their ends to bands made of any desired fiexible material, such as leather, canvas, or duck.

In practice the delivery-rolls 5 may be made upon a separate machine, the hemp being taken from the endless apron by an operator, who shakes it free of hurds before it is subjected to the crushing effect of therolls 5.

d represents a fender above the feed-table 3.

f represents a fender, which prevents the hurds from being thrown or blown forward in the way of the operator.

h represents a fender which prevents the hurds from being thrown or blown forward after they have passed over the endless apron.

Having described my invention, what I claim isl. In a hemp-brake, the combination of the rotary riddle breaker having separate revolving arms 8, feed-rolls, and stationary breaker-bar 7,arranged between the feed-rolls and riddle-breaker, an open endless carrier arranged below the riddle-breaker, and the delivery device at the rear end of said endless carrier, substantially as specified.

2. In a hemp-brake, the combination of a rotary riddle-breaker having separated arms 8, a pair of feed-rolls 2, a stationary breakhar 7, arranged between the feed-rolls and the rotary riddle-breaker, an endless traveling carrier 10, arranged below the rotary riddle-breaker, a pair of delivery-rolls 5, arranged at one end of the endless carrier, and a series offenders interposed between the other end of the endless carrier and the stationary break-bar, substantially as described.

In testimony whereof I have hereunto set my hand.
